Cylinder 4 misfire code detected

So i have a few things i could use some help with. My check engine light was on and got it checked and the cylinder 4 misfire code came up, and did my reasearch what could be the issue but still having some trouble, my car hesitates lightly some days more than others, loses little power when accelerating, if i turned it off than try and start it than it will only stay started for like 2 seconds than turn off unless i give it gas, itll get hot than cool back down but this is consistently, slip gears a little, these are just some things ive noticed, i cleaned my throttle body and it took care of everything for about 10 mins after driving it, spark plugs are good, pretty sure the throttle body position sensor is good after checking it, trying to find source of the problem but need some mechanics advice on what to try, please help, thanks in advance!
